7 Claims.

This invention relates to strollers of the type which may be propelledby a child while seated in the stroller or which may be propelled by anadult.

It is an object of this invention to provide a baby walker or strollerwhich may conveniently carry more than one child.

Another object is to provide a stroller in which two children may beseated in tandem seats.

Another object is to provide a stroller having an improved wheelmounting.

A further object is to provide a stroller having an improved springconstruction.

A further object is to provide a stroller hav ing an improved frontwheel suspension.

A still further object is to provide a stroller or baby walker whichwill be more economical to manufacture.

vA still further object is to provide a stroller or baby walker whichwill be strong and sturdy, and yet light in weight.

Other objects will become apparent upon considering the followingspeciiication.

A structure embodying the invention is illustrated in the accompanyingdrawings and will be fully described hereinafter, the invention residingin certain novel features which will be particularly pointed out in theappended claims.

In the drawings:

Fig. 1 is a plan view of a tandem baby walker embodying the invention;

Fig. 2 is a side elevational view of the Walker shown in Fig. 1;

Fig. 3 is a front view of the walker shown in Fig. l;

Fig. 4 is a detail of the rear axle and is a rear View of the walkerwith other parts broken away;

Fig. 5 is a front view of a modified form of front wheel suspension; and

Fig. 6 is a side view of the structure shown in Fig. 5.

In the drawings, and referring particularly to Figs. l to 4 inclusive,the baby walker, or stroller, is built on a base I0, which is formedwith two seats II and I2 in tandem, Fig. 1, each seat being adapted toaccommodate one child. Back rests I4 and I5 are provided for the frontand rear seats, respectively, to enable the child to lean back incomfort.

The base IIJ is supported from the ground by a pair of caster wheelsI'I--I'I at the front of the base I 0 and a pair of wheels I8-I8 at therear of the base I0.

The wheels I8-I8 at the rear end of the stroller are carried on an axle-20. The axle 20-20 is divided at the center of the stroller and extendshorizontally as at 2| (see Fig. 4) to receive the wheels I 8-I 8. Theinner ends of the axle 20-20 are joined together by a sleeve 23 and heldby cotter pins 24-24.

The horizontal portions 2I of the axle 20-2 extend through the wheelswhich may be secured 2 thereon in any convenient manner, such as bycotter pins 25-25.

The outer ends of the axle 20-20 extend through the wheel and curvebackwardly and up as shown at 26-25 over the wheel and terminate invertical projections 2I-2'I which pass through the base I0. `The curvedportions 26 act as guards for the wheels and protection for furniture.

The vertical projections 21--21 have washers 29-29 fixed thereon, whichseat the lower ends of springs 30-30. The upper ends of the springs3EI-30 support the base I0 and provide suitable resilience for the seatsII and I2 to absorb road shock from the rear wheels.

The upward movement of the seat on the projections 2'I-2'I is limited bywashers 32-32 xed on the projection. The portion of the projections21-21 above the washers 32-32 pass through reinforcing ribs in 33-33 inthe back rest I5 and are secured to a retaining rod 35 which passesthrough the back I5 and forms a support for both back rests I4 and I5and a guard to retain children in both seats II and I2.

The forward back rest I4 is secured to the base II) at the lower end andhas a support rod 31 passing through the upper end. Both ends of the rod31 are secured to the rod 35, which supports the back rest I4.

The front ends of the rod 35 are joined together at 39 and have a rod 40secured thereto at the junction 39, preferably by welding.. The rod 40extends downwardly and passes through the base IIJ adjacent the frontend thereof.. The base II'I is held in xed position relative to the rod40 by a washer 42 secured on the rod 40.

The rod 40 extends vertically downwardly from the base I0 and isreceived in a sleeve 45 which supports the front wheel assembly. Aspring 41 is interposed between the top of the sleeve 45 and the bottomof the base I0 to provide suitable resilience for the base.

The front wheel structure is built on a curved bumper rod 50, which hasdownturned ends 52-52 which form pivotal supports for the front casterwheels I'I. Suitable springs 53 are interposed between the bumper 5I]and the caster wheels to absorb road shock. The bumper rod '5B has acurved strap support 54 xed at its outer ends to the outer portions ofthe bumper rod. The center of the support 54 is connected with the baseby means of a bolt 55, which passes through both the base I0 and thestrap support 54. A nut 5l retains the base II) and the support 54assembled. A spring 59 is interposed between the base lo and the support54 to absorb road shock.

A reinforcing member Si) comprising a pair of rods 60 and Ell isconnected to the central part of the bumper 5B and to the sleeve 45. Theends of the rods 60 and 60 are bent outwardly and are connected to thesupport 54 by Welding.

:axles 11 which receive Wheels 19.

A foot rest B3 is carried between the top of the sleeve 45 and the rearaxle, and provides a support for the childrens feet when the stroller isbeing propelled by an adult.

A handle 6'5 may be formed of two rods 65 and 65 spot welded together toform the body of the handle. The lower ends of the handle are spreadapart and are attached to the opposite sides of the stroller on theextension of the ames 20-20 above the curved portions 2G-26. A support61 joins the top of the rear back rest I5 with the rods BEC-SB.

The upper ends of the rods 55-65 are also spread apart and are securedin that position by a hand bar 68.

In the form of the invention shown in `fig. 5 and 6 an alternateconstruction for the front wheels is shown.

Referring to Figs. 5 and 6 the rod d0 projects downward verticallythrough the base I0 and is received in a sleeve 10. A spring 1i isinterposed between the top oi' the sleeve 'l0 and the base I0 to absorbthe road shock from the front wheel.

An axle rod 13 is fixed at its center to the sleeve by welding or othersuitable means. The axle rod curves downwardly and rearwardly andterminates in a pair of alined horizontal The axis of rotation of thewheels being offset from the vertical axis of rotation about the rod 49permits the front end of the stroller to move in the direction urged.

In practice the stroller may be used with the handle 65 and the footrest 63 to transport one or two children. As an alternate method of use,the handle 65 and the foot rest 63 may be removed and one or twochildren be placed in the stroller and permitted to propel it by meansof their feet. In this action the bumpers 26 and 50 act to protect thefurniture.

It will be realized that the hereinbefore described form of theinvention is to be taken merely as a preferred embodiment thereof, andthat various changes in size, shape and arrangement of parts may be madewithout departing from the spirit of the invention or the scope of thesubjoined claims.
